DMM Big Boa Keylock Locksafe

This is the ‘Big Daddy’ of lockers - the ultimate rigging biner and one which is super strong and super tough.

It is large enough to accommodate several knots and has a very wide gate opening -just what you need in a rigging situation.

Despite its name, the Big Boa is surprisingly light; by giving it an I-Beam construction DMM has reduced the overall weight by almost 25%. Add in the fact that it is easy to handle in gloves and the appeal to winter climbers is obvious.
